"Empty Garden (Hey Hey Johnny)" is a song composed and performed by English musician Elton John, with lyrics by longtime collaborator Bernie Taupin. It originally appeared on John's 1982 album Jump Up!. The song is a tribute to John Lennon, who had been shot and killed one and a half years earlier.

After Lennon's death, John was concerned that a tribute song to the late Beatle would be "clumsy" – until he saw Taupin's lyrics. The song is titled "Empty Garden", as Lennon's last live performance was at Madison Square Garden (with John in 1974). It has been said that the line "Can't you come out to play?" is a reference to Lennon's song Dear Prudence.

John wrote and recorded an earlier instrumental tribute to Lennon, "The Man Who Never Died", which was issued as the B-side of "Nikita" in 1985 and eventually included as a bonus track on the remastered reissue of Ice on Fire.

Elton has rarely performed the song live, after the 1982 world tour, because it brings back many painful memories of Lennon's murder, as he once stated during a concert on November 5, 1999, at the Kohl Center in Madison, Wisconsin, and prior to that at a concert on October 9, 1988 at The Centrum in Worcester, Massachusetts. In the latter case, John played the song, as well as "Lucy in the Sky with Diamonds," in his third encore to mark what would have been Lennon's 48th birthday.
